The only controller I know of that can mix SATA and IDE in a RAID array is nVidia's.

Dont put your raptor in a RAID array with those other drives. The raptors average seek time is waaaaaaaaay better than any of those 7200RPM drives, but if you put them in a RAID0 array the seek time becomes that of the slowest drive in the array. A RAID array is only usefull when handling huge files (video or large audio), otherwise you will not notice an increase in performance. In fact I think if you had the raptor as a stand alone drive and then put it in a RAID array you would actually notice a decrease in performance.
